Yes, the problem is from " Mac + 64-bit indices + --with-clanguage=C++"
In Fande's case, PetscInt (int64_t) is "long long int" but MPI_Count is
"long int". Though both are 64-bit, they are different in C++ function
resolution.
$ cat test.c
extern int foo(long long *);
void bar() {long a = 0;

I used MPIU_Ineighbor_alltoallv() to wrap MPI_Ineighbor_alltoallv() or

I'm not sure why we have PetscSFCount - and not always use MPI_Count.
Maybe this would work?
Perhaps Junchao can clarify

We do have such builds in CI - don't know why CI didn't catch it.
$ grep with-64-bit-indices=1 *.py
arch-ci-freebsd-cxx-cmplx-64idx-dbg.py: '--with-64-bit-indices=1',
arch-ci-linux-cuda-double-64idx.py:'--with-64-bit-indices=1',

OK, this works for me.

What MPI is this? How to reproduce?
Perhaps its best if you can send the relevant logs.
The likely trigger code in sfneighbor.c:
/* A convenience temporary type */
#if defined(PETSC_HAVE_MPI_LARGE_COUNT) && defined(PETSC_USE_64BIT_INDICES)
typedef PetscInt PetscSFCount;
#else
It seems correct according to
#define PETSC_SIZEOF_LONG 8
#define PETSC_SIZEOF_LONG_LONG 8
Can not convert from "non-constant" to "constant"?

Hi All,
When building PETSc with 64 bit indices, it seems that PetscSFCount is
64-bit integer while MPI_Count is still 32 bit.
typedef long MPI_Count;
typedef PetscInt PetscSFCount;
I had the following errors. Do I have a bad MPI?
Thanks,
Fande
